Example program 1 – activating message texts with a
Boolean variable
The program consists of seven screens that can be selected
using the Cursor buttons
Í
and
Ú
. The screen change was
defined in the Button editor (
Page 331). The circuit diagram uses six on-delayed timing
relays that activate outputs Q1 to Q4 and LED03 in
succession after an elapsed time. This operation is run in a
continuous loop since timing relay T06 resets all timing relays
after a set time. The message texts are controlled in all
screens by means of Boolean variables. As these only have
two states (0/1), only two different messages can be output
via each message text element. If other variable types are
used, the number of possible message texts can be increased
accordingly.
